New Griffin Armament DUAL-LOK Rifle Suppressors

Suppressors offering active retention systems are often times demanded by government customers and Griffin has spent considerable research and development efforts to engineer and manufacture a next-generation system in this category. 

A quality mounting system should be accurate, robust, reliable, require minimal training, and be free of wear-prone metal on metal teeth or ratchets, thereby guaranteeing a long trouble-free service life with minimal maintenance needed. Griffin’s patent-pending DUAL-LOK mounting system was designed around these objectives.  The suppressor itself should have a minimal flash signature, minimal weight, minimal POI shift, minimal gas blowback, maximum strength, durability, and sound performance.  These were the company’s internal performance categories that were used to create the new DUAL-LOK silencers from Griffin Armament. 

Griffin Armament was the US pioneer of tubeless suppressor technology when in 2010, nearly the whole Griffin centerfire suppressor line was tubeless. If you want to achieve lower system weights, tubeless construction is ideal, as traditional double-walled construction is omitted. Deleting the outer tube saves weight but also imposes other engineering difficulties that must be overcome.

However, with over a decade of tubeless suppressor manufacturing experience, Griffin has matched or exceeded the durability and useful service life of traditionally constructed suppressors of yesteryear. High-quality materials from industry-leading suppliers, cutting-edge CAD design, industry-leading tooling and machining practices, and integration of laser welding provide needed repeatable and ideal weld strength to the tubless DUAL-LOK suppressors

Internal flow and balancing of optimized sound suppression is also a fundamental study in suppressor engineering, as that is the chief reason for using a suppressor. Griffin has integrated its patented ECO-FLOW baffle design into these suppressors. This design provides optimal flash reduction and flow, which reduces blowback in semi-automatic and full automatic operating systems. This design provides the end user with reduced sound pressure and gas at the shooter’s ear and face, a more enjoyable shooting experience. The patent pending flash hiding end cap features high-performance internal and external flash reducing features as well as optimally tuned gas vents which not only enhance flash reduction even further but also increase sound performance to ECO-FLOW baffles.

The DUAL-LOK mounting system is machined into the suppressor body for maximum accuracy and durability. It features a precision taper interface (one locking feature) between the mount and the device, ensuring accuracy and repeatable POI shift. An ACME thread provides speed and ease of attachment. A robust 718 Inconel wave spring provides a reliable and positive heat-resistant spring action to the redundant locking collar (second locking feature). The locking collar is semi-permanently installed to the mount via factory-pressed splined taper pins. Since the mount has no wear-prone metal-on-metal sliding actions like many other mounts, there is no need for the operator to disassemble the system. This locking ring includes three anti-rotation teeth, which ensure the suppressor will not come off inadvertently. The muzzle device integrates 60 machined anti-rotation splines, which are doubled by the collar’s two locking positions.

How is this achieved? The collar’s two locking positions are machined out of phase of one another by 3 degrees which provides the system with 120 different locations to lock and ensure that when the suppressor is firmly screwed onto the taper, a locking spline will be at an ideal location to ensure a rigid and locked suppressor. When the suppressor is firmly attached, only one of the two lock positions will work, allowing the spring to push the locking collar rearward over the splines. Every time the operator attaches the suppressor, they will articulate the collar to this same locking position.

Griffin Armament DUAL-LOK
It is easy to tell when the locking system is engaged.

“The DUAL-LOK suppressors are world-class, cutting edge suppressors second to none. I have been obsessed with silencer research and design from a young age. I was bent on combining the best available technology from every facet of our R&D into one product family. We are dedicating ourselves to this product group moving forward. Expect to see it prevalent throughout the industry for years to come. I have confidence that demanding customers will be well satisfied by this invention.”
